According to one preferred embodiment of the present invention, the residue dryer includes a cooling water reservoir for cooling the residue to prevent explosion of the residue.

Hereinafter, with reference to the accompanying drawings will be described in more detail the waste tire pyrolysis oilification apparatus of the present invention.

Figure 1 is a schematic diagram showing the structure of the waste tire pyrolysis oilification apparatus according to an embodiment of the present invention. According to FIG. 1, the waste tire passes through a pretreatment device consisting of a bead wire removing device 12, a primary grinder 14, a TROMEL SCREEN 16, a secondary grinder 18, and an iron core separator 20. In the above process, the iron core is stored in the iron core storage tank 22, and the waste tire separated from the iron core is crushed into a powder form and stored in the waste tire storage tank 24. The waste tire is transferred from the waste tire storage tank 24 to the metering tank 30, and then introduced into the reactor 100 by two electric valves 32 installed under the metering tank 30. As the upper valve 32a of the two electric valves 32 is opened, the waste tire of the fixed quantity stored in the fixed-quantity injection tank 30 is moved to the intermediate storage tank 34, and when the movement is completed, the upper electric valve 32a is completed. ) Closes. Nitrogen purging is carried out in the intermediate storage tank 34 for 2 to 3 seconds to prevent air from being introduced in the above process, and then the lower electric valve 32b is opened to inject the quantitative waste tire into the reactor 100. In addition, the waste tire is supplied from the oil tank 26 so that the waste tire and the waste oil in a powder form are mixed at a ratio of 2: 1 to 3: 1, and are introduced into the reactor through the oil inlet 106 to waste the waste tire. To precipitate. Simultaneous pyrolysis of waste oil and waste tires has the advantage of shortening the pyrolysis treatment time of the waste tires by acting as a swelling agent.

As it passes through the reactor 100, the waste tires are pyrolyzed and discharged through their respective outlets in the form of oil vapor and residues. The oil vapor is stored in the oil reservoir 42 through the oil condensation system 40 as heavy oil and light oil, and the non-condensable gas is stored in the gas holder 44 and then sent to the hot stove 38 for use as fuel. do.

After the pyrolysis operation while passing through the reactor 100, it is introduced into the residue dryer (200). At this time, the residue is quantitatively inputted through the intermediate reservoir 34 by the two electric valves 32 as when the waste tire is introduced into the reactor 100. The hot gas discharged while passing through the reactor 100 and the residue dryer 200 is sent to the hot stove 38 to be reused as a heat source, and the oil vapor is stored in the oil reservoir 42 via the oil condensation system 40. do. The non-condensed gas is stored in the gas hold 44 and, if necessary, sent to the hot stove 38 for reuse as a heat source.

The last remaining residues are sent to the secondary residue dryer 200 and operated in the same manner as in the primary residue dryer 200 to discharge and process the last residues.

The last residue after the two drying process has a high temperature near the final temperature of 500 ℃, there is a risk of explosion when exposed to room temperature directly through the outlet. Therefore, the final residue discharged from the secondary residue dryer 200 is first stored in the intermediate reservoir 34 located between the electric valve 32 and the feed feeder 46, and periodically by the feed feeder 46. As a result, a certain amount of residue is immediately discharged into the cooling water reservoir 48.

By installing the cooling water storage tank 48 it is possible to block the exposure of high-temperature residue in the air at room temperature, and to obtain the effect of blocking the inflow of air through the discharge pipe. The cooled residues are stored in the residue storage tank 52 through the transfer conveyor 50 installed in the cooling water storage tank 48 and are utilized as energy sources through a separate processing system.
